Anti-theft Devices problems of the 2003 Nissan Maxima

Nissan xenon (hid) headlights stolen, second time in three days. After the first incident, Nissan installed an anti-theft system which should have prevented theft. But that did nothing. Vehicle lights were stolen during daylight in heavy populated area. This is becoming very frustrating, especially because of its frequency. Safety concerns should be considered because individuals with these Nissans are driving with no headlights when stolen, no lights no turn signals. Nssan motor will not offer any assistance to aide in solving this problem, upon calling them they basically said they could not assist.
